What is the HSN Code for Installation Services?

For services, India uses SAC codes which are similar to HSN. Installation related services generally fall under:

  • SAC 9987 for maintenance, repair and installation services
  • SAC 9954 for construction services involving installation in buildings

Which one you use depends on the nature of installation work.

How Product Installation is Classified Under HSN (SAC)?

When you install a product like an AC or machine at a customer location, the activity is usually covered under SAC 9987 if:

  • You are not constructing a building or civil structure
  • You are doing standalone installation or commissioning work
  • The main object is to fix or start the equipment at site

If the installation is part of a bigger construction project, the same work may be treated as part of works contract under SAC 9954.

Home Installation Services and Their HSN Code

Typical home installation services include:

  • Air conditioner fitting
  • Geyser installation
  • RO and water purifier installation
  • TV wall mounting and similar services

Most of these household installation jobs are billed under SAC 9987. Many businesses mention 9987 on invoices for such services and charge standard GST.

GST Implications on Installation Services

Under GST, installation services are usually taxable at the standard rate unless a special exemption or concessional rate is given. For most installation work:

  • GST is 18 percent
  • The same rate applies to labour charges for installation
  • Material used may be taxed separately if billed separately

If the installation forms part of a composite supply with goods, you must see whether the principal supply is goods or service and classify accordingly.
